AWNING-FIXTURE.

Application filed October 30, 1916.

To all whom it may concern:

Be it known that I, Davn) H. HARNLY, a citizen of the United States, andresident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Awning-Fixtures, ofwhich the following is a specification, and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to awnings and more particularly to those whichare wound upon a spring roller. The object of the invention is toprovide an improved fixture for holding the awning in extended position,the improvement residing more especially in a construction which permitsan automatic release of the awning from the fixture when the awning isto be raised.

In the accompanying drawings,

Figure 1 is a perspective view showing an awning equipped with one formof the improved fixture.

Figs. 2, 3 and 4 are front elevations of the improved fixture showingthe movable part of the same in different positions, the associated partof the awning rod being shown in section and a further position of themovable part of the fixture being shown by dotted lines in each of thesaid views.

Fig. 5 is similar to Fig. 2, but shows a difierent form of the improvedfixture, and

Fig. 6 is a side elevation of the parts shown in Fig. 5.

The drawings illustrate the use of the improved fixture in connectionwith an awning which is wound upon a spring roller 10. This roller is ofWell known construction and comprises the usual concealed spring 11. Itis shown as being extended between the two sides 1213 of the windowframe near the top of the window. The awning 14: is also of a familiarform, having its lower end mounted upon the cross piece 15 of an arch16. The two ends 17-18 of the arch 16 slide in grooves, as 19, in a wellknown manner.

When the awning 1 1 is completely raised the arch 16 occupies an uprightposition in the plane 'of the window frame with the cross piece 15 ofthe arch extending along the underside of the roller 10. When the awningis lowered the ends 1718 of the arch 16 slide in the grooves, as 19,until the lower ends of the said grooves are reached. The cross piece 15of the arch then swings outwardly to support the awning in Specificationof Letters Patent.

extended position. If desired a guide rod 20 may be extended between thetwo sides 1213 of the window frame in front of the awning to confine theextension of the awning to that part of the same which is below the saidrod. The awning 11 may also be drawn down to a position in which thearch 16 is inverted at the lower end of the window and the entire awningis extended in the plane of the window. This last mentioned position ofthe awning serves for darkening the room.

The improved fixture provided by the invention is employed formaintaining the arch 16 in the horizontal position illustrated inFig. 1. The form of construction illustrated in Figs. 1 to a inclusivemay also be used for maintaining the arch 16 in a downwardly inclinedposition indicated in Fig. 3. The last mentioned position of the arch 16corresponds to a depressed position of the awning for shutting out a lowsun without darkening the room. As the spring roller 10 serves to raisethe awning, the improved fixture is only required to resist upwardmovement of the arch 16. i

In carrying out the invention a notched plate, as 21, (Figs. 1, 2, 3 and4:) or 22, (Figs. 5 and 6) is mounted to swing across the path of eachof the end portions, as 17-18, of the arch 16. As shown, each of theplates 21 or 22 is supported in front of the corresponding side 12-13 ofthe window frame at substantially the same elevation with the lower endof the groove, as 19. For this purpose a bracket 23 having an inturnedouter end 24L, is secured against each of the side members 12-l3 of thewindow frame to project outwardly therefrom and each of the plates 21 or22 is pivotally secured against the end 24 of the corresponding bracket23.

I11 the form of construction illustrated in Figs. 1 to a the pivot, as25, is located between the ends of the corresponding plate 21 and isonly sufficiently removed from the mid-length of the plate to permit theplate to assume a definite position by gravity. WVhen so mounted theplate 21 is preferably provided with notches 26 and 27 at its upper andlower ends respectively. In the normal position of the plate 21, thenotch 26 opens upwardly at one side of the path of movement of thecorresponding end portion, as 17, of the arch 16. Under thesecircumstances the upper end portion, as 28,

of the plate 21 extends over the inner end of the notch 26 in the formof a hook for engagement with the arch. On the other hand, that portion,as 29, of the plate 21, forming the other wall of the notch 26, extendsinwardly beyond the end of the hooked por tion 28 and provides anabutment for engagement. by the corresponding end portion, as 17, ot'the arch for swinging the plate during downward movement of the arch. Inthe gravity supported position of the plate 21, the notch 27 facesdownwardly and is located directly in the path of movement of thecorresponding end portion of the arch 16. Under these circumstances thenotch 27 is entered by the corresponding end portion, as 17, of thearch, during the upward movement of the arch, to turn the plate forpermitting the arch to pass by the plate.

In the form of construction illustrated in Figs. 1 to 4 the plate 21 mayalso be formed with a third notch, as 30. As shown, the notch 30 facesinwardly when the plate 21 occupies the position illustrated by dottedlines in Fig. 2. It follows that if the arch 16 is lowered to a positionin which its end portions 17-1S have cleared the parts 29 of thecorrespondii-ig plates 21, but have not been cleared by the adjacentsidewalls, as 31, of the notch 27, the end portions of the arch willenter the notch 30 when the arch is released. This position of the partsis illustrated by full lines in Fig. 3, the arch being held in adepressed position providing a lowering of the awning for obscuring alow sun without darkening the room. For releasing the arch from thisposition it is only necessary to lower the awning through a sutficientdistance to permit the end portions 1718 of the arch to enter thenotches 27 of the corresponding plates 21. Upward movement of the archresulting from the winding of the awning upon the spring roller 10 will.then serve to rotate the plates 21 to the position indicated by fulllines in Fig. 1, thereby permitting the arch. to pass by the saidplates.

In the form of construction illustrated in Figs. 5 and 6, the pivot, as32, by which each plate 22 is secured against the end portion 2-l of thecorresponding bracket 23, is located near the top of the plate. Underthese circumstances the plate 22 has but one notch, as 33, and thisnotch faces inwardly in the normal position of the plate. As shown, thatpart as 3st, of the plate 22 which constitutes the bottom wall of thenotch 33, projects inwardly beyond the part 35, forming the upper wallof the notch, and the part 35 is curved downwardly to form a hook forengagement with the corresponding end portion, as 17, of the arch 16.This form of construction requires that the swinging movement of theplate 22 should be limited in one direction, as by the formation of astop lug 36 upon the plate for engagement with the bracket 23. This formof construction also requires that the lower margin, as 37, ot the plate22, should be beveled for cam engagement with the corresponding endportion, as 17, oi the arch.

In using the form of construction illustrated in Figs. 5 and 6, theawning is maintained in extended position if lowered only far enough tobring the end portions, as 17, of the arch 16, in front of the mouth ofthe notch 33 in the corresponding plate 22. During downward movement ofthe arch to this position the plate 22 is swung outwardly by a camengagement'ot the adjacent end portion, as 17, of the arch, with themargin of the plate above the notch 33. If the downward movement of thearch 16 is arrested when itsend portions, as 17 are each in line withthe mouth of the notch 33, the plate 22 will be returned by gravity toenter the end portion, as 17, of the arch in the notch. On releasing theawning the hooked 7 wall 35 of the notch becomes engaged with thecorresponding end portion, as 17, of the arch for maintaining the awningin extend.- ed position. When it isdesired to raise the awning, it mustfirst be lowered to a position in which the end portion, as 17 of thearch, may be engaged with the oblique margin, as 37, of the plate 22. Onbeing released from this last mentioned position, the winding of theawning upon the spring roller 10 serves to raise the arch 16 quickly andthe plate 22 is swung outwardly to permit the adjacent end portion, as17, of the arch, to pass by without entering the notch 33.

In both of the forms of construction illustrated'in the drawings theswinging of the plates 21 or 22 is entirely automatic; It is accordinglyunnecessary to reach through the window for the manipulation of theseplates and no cord or other releasing device, extending through'thewindow, is required. l
